Abstract

(57) [Abstract] [Purpose] To provide a cyclone dust collector with a high dust collection effect that can remove even fine dust. [Structure] A nozzle is provided in the upper part of a dust collecting cylinder of a cyclone dust collector, and water is sprayed from the nozzle, and the sprayed water droplets are mixed with dust-containing air and placed on a swirling flow to collect fine dust. Further, the remaining dust-containing water droplets and floating dust are removed by a filter made of stainless steel scrubber provided in the exhaust stack.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cyclone dust collector.

[0002]

[Prior art]

 Conventionally used cyclone dust collectors remove dust that has been sucked into the dust collecting cylinder by separating it into a swirling flow.

[0003]

[Problems to be solved by the device]

 However, the fine dust cannot be sufficiently separated only by the swirling flow, and the fine dust that cannot be separated is discharged to the outside together with the exhaust gas. In order to remove fine dust, it was necessary to guide the exhaust gas to another dust collector, such as a bag filter dust collector, which required double equipment. This proposal was made to eliminate this drawback, that is, to a cyclone dust collector that has a higher dust collection effect than conventional cyclone dust collectors and that can also remove fine dust.

[0004]

[Means for Solving the Problems]

 That is, the present invention relates to a cyclone dust collector characterized in that a nozzle is provided in the upper part of the dust collecting cylinder, water is sprayed from there, and the sprayed water droplets are mixed with dust-containing air and placed in a swirling flow. is there. Further, the present invention relates to a cyclone dust collector in which a filter for collecting residual floating dust and water droplets containing dust is provided in the exhaust pipe above the dust collecting cylinder. It also relates to a cyclone dust collector whose filter is a stainless steel scrubber. That is, the present invention relates to a cyclone dust collector that has the effect of adding dust removal effect of a spray mixed flow to dust removal by cyclone, and in addition, inevitably removing fine dust in exhaust gas containing water by a filter.

[0005]

[Action]

 The water droplets ejected from the nozzle provided in the upper part of the dust collecting cylinder are mixed with the sucked dust-containing air and become a mist to form a swirling flow, which is a fine particle that cannot be removed by a conventional dust collector. Dust is also collected to further enhance the dust collection effect. Furthermore, the residual floating dust and dust-containing water droplets contained in the exhaust gas are also collected by the filter provided in the exhaust stack.

[0006]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. As is well known, in a cyclone dust collector, the dust-containing air is sucked into the dust collecting tube (1) through the dust hose (6), first descends into a swirling downward flow in the dust collecting tube, and then is collected. It reverses in the lower part of the dust cylinder and rises as an ascending flow to the exhaust pipe (10) to reach the exhaust port (4).

In the present invention, the nozzle (2) is provided in the upper part of the dust collecting cylinder, and water is jetted from there. The water droplets (3) ejected from the nozzle are mixed with dust-containing air to form a mist, which forms a swirling downward flow, descends while collecting dust, and becomes dust-containing wastewater (lower drainage outlet ( Drained from 7). Furthermore, some dust-containing water droplets and the remaining suspended dust will flow up to the upper part of the stack (10), but the filter (5) also collects the suspended dust and water droplets containing dust, resulting in cleanliness. Air is discharged to the outside.

It should be noted that a stainless steel scrubber is used for the filter (5) so that the filter (5) can be easily removed to have a cleaning and replacement attachment structure. In the present embodiment, the number of water jet nozzles (2) provided in the upper part of the dust collector is one near the attachment portion of the dust hose and one on the opposite side, but the position and number can be changed. Is.

[0007]

[Effect of device]

 As described above, according to the present proposal, by using sprayed water droplets for dust removal and providing a filter at the exhaust port, it is possible to remove even fine dust that could not be removed by conventional cyclone dust collectors, and the dust collection effect. Can be further increased. Therefore, it is not necessary to use another dust collector (tack filter type dust collector) as in the conventional case, and the facility can be further simplified.
